Gtuner is a gtk/gnome based radio card tuner that has support for numerous different radio cards as well as the kernel drivers. It has a large feature list including: a scriptable GUI, themable panel applet, a 7 day alarm, an almost unlimited number of channels, gnome support, full GUI configuration and much more.
GtkGLMaterialDialogis a GTK+ dialog that can be used to edit 3D-object material properties. It is based on the material properties of OpenGL with diffuse, ambient, specular, emissive colors (RGBA), and a specular coefficient (shininess). The material is previewed by rendering a lit OpenGL sphere in a gtkglarea widget.
GtkSC is a GTK/Perl based application for viewing the list of streams available via SHOUTcast without waiting a long time for Netscape to draw the HTML tables. It will launch your favorite MP3 player and play the selected stream (provided you have an MP3 player capable of playing HTTP streams)
grunch is a package of scripts and software which can take a pair of side-by-side partial scans of an image, and merge them into a single image without leaving an obvious seam. It was written to allow LP record jackets to be scanned using an ordinary single-page flatbed scanner. It requires the pbmplus/netpbm tools, and the bash shell. grunch should compile and run correctly on almost any Unix-type O/S which supports these tools.
GSI is an easy-to-use network audio system that gives applications, through a very simple API, sample playing with stereo, 3D, doppler effects, music playing (MIDI, HMP, MUS), and CD playing and ejecting/changing. GSI also contains a separately usable sound/music loading/saving/format conversion library libgsif, although saving/format conversion is not completely done. It is known to run on Linux, OpenBSD, and FreeBSD, with support for /dev/audio (8000Hz mono mulaw), OSS, ultrasound project drivers, and FreeBSD's pcm system (from 0.9.4 on).
Gstring is yet another guitar tuning application. It requires a soundcard, a microphone, the FFTW package, and if you want a GUI, the Gtk+ toolkit and a new Gtk+ widget called GtkDatabox. A non- Gui version called "string" is included in version 1.0.0 and dynamically linked binaries (for i386 machines) are included as well.
gsyn is internally designed to be an extensible, modular synthesizer, but the interface and current codebase present a Roland TB-303 emulator which is programmed using fasttracker-style note entry. It also features delay reverb and distortion, so the sound is comparable to Propellerhead's ReBirth RB-338. gsyn has been compiled and tested under Linux 2., IRIX 6.2, Solaris 2.6, Windows 95, and Windows NT.
Gte is a Texture editor for the POVray raytracer. You can create a texture's declaration in POVray's language by means of normal text or via Tk Widgets adapted for this special usage. You can also make a test rendering with selected lights, and store and retrieve previous declaration statements.
